Definitions
- RPVs Popular game applications for RPVs may include racing and pursuit games. These games generally involve a number of players each with his own RPV system which includes two stations, a first station the RPV, for example a drone, and the second station a remote control base unit for controlling the drone. Some systems may include a display on the remote control base unit to view the images and other information which may be received from the drone while other systems may include viewing glasses which may be worn by the player or other display means in addition to, or in lieu of, the display on the base unit.
- FIG. 1 schematically illustrates a typical game application scene 10 with multiple RPV systems and interference sources.
- RPV system 12 A includes an RPV 14 A and a remote control base unit 16 A
- RPV system 12 B includes RPV 14 B and a remote control base unit 16 B.
- Uplink and downlink communication may include control data on the uplink, and video and other data which may be related to the operational status and/or position of the RPV on the downlink.
- Transmissions from base unit 16 A or from RPV 14 A may cause interference 22 in CH 2 , as indicated by hatched arrow 18 B, and may affect the performance of RPV system 12 B. Additionally or alternatively, other RF transmissions may cause interference, for example, from a radar station 20 which may cause interference 24 in CH 2 .
- a method of controlling channel interference in a plurality of wireless communication systems in geographical proximity may include allocating a pool of frequencies among the wireless communication systems, wherein each system may be allocated a set of one or more frequencies for selecting on which frequency to operate and wherein at least one of the sets of frequencies may include more than one frequency. At least two of the allocated sets may be different from each other.
- the method may additionally include storing and organizing information in a database to perform the allocation.
- the wireless communication systems may include RPV (remotely piloted vehicle) systems and may include RPV drones.
- the database information may include a location and a time of operation of the wireless communication systems.
- the database information may include information about channels occupied by interference sources other than the wireless communication systems.
- the database information may include information about the number of wireless communication systems in geographic proximity.
- the method may include allocating a maximum output power limit for at least one the of the wireless communication systems on at least one of the frequencies of its allocated set of frequencies.
- FIG. 4 schematically illustrates another exemplary spectrum management system, according to an embodiment of the present invention.
- FIG. 5 is a flow chart of an exemplary method of setting an event associated with a RPV game using the spectrum management system, according to an embodiment of the present invention.
- the spectrum management system in these types of installations controls the frequencies of the access points (again, each access point is given a single frequency) and the users are free to use whatever frequency that they want.
- a problem which may arise is channel interference as two (or more) users may operate on a same channel.
- a wireless spectrum management system which includes a spectrum manager which may allocate each RPV system a set (list) of several channels from which a RPV system may select between channels according to channel conditions, each set being different for each player.
- the channels may be sufficiently spread out one from the other to avoid interference between the players or alternatively, the channels may be overlapping.
- the spectrum manager may allocate power level limits to the different channels allocated to each player to limit RPV system power output to prevent cross-channel interference. It may be appreciated that allocating power level limits to the different channels may be particularly advantageous when channels may overlap or when they are very close together.
- the allocation of channels and/or power may also take into consideration the channel requirements of potential sources of interference which may not be controlled by the spectrum manager. These may include, for example, game non-players, players and non-players associated with a different game (or games) being played in close proximity, and also outside interference sources which may include radar systems, among other potential sources of interference.
- the total number of allocated channels may be greater than the total number of RPV systems and, optionally, also the potentially interfering sources.
- the list of channels may be prioritized, the priority level of each channel determined by the spectrum manager so that a RPV system may select a lower priority channel only if a higher priority channel is occupied by another RPV system or by a potentially interfering source.
- the spectrum manager may include a central manager which may delegate some or all of its functions to local managers who may be responsible for allocating channels “on-the-fly” that is, based on real-time sensing of channel conditions. Additionally or alternatively, the local managers may allocate frequency and power limits for the various channels “on-the-fly”. Additionally or alternatively, the local managers may provide sensing information directly to the central manager for updating channel and/or power allocations.
- wireless spectrum managements system disclosed herein is described with reference to RPV systems, the system may be readily implemented for other types of wireless communication systems which operate geographically proximal to one another and may, as a result, suffer from channel interference due to their proximity. It may be further appreciated by the skilled person that such a spectrum management system may additionally be used in RF environments which include potentially interfering sources which may not be controlled by the manager and which may interfere with the geographically proximal wireless communication systems.
- Spectrum management system 100 may be server based (server may be included in spectrum manager 102 or may optionally be a separate server), optionally cloud based as depicted by cloud 106 , and may allow spectrum manager 102 to transfer data to, and receive data from, computing devices associated with the different RPV systems.
- the computing devices may include but not be limited to, for example, laptop computers as shown by LT 108 associated with RPV SYS 1 , mobile phones as shown by MOB 110 associated with RPV SYS 2 , tablets as shown by TAB 112 associated with RPV SYS 3 , and dedicated devices specifically designed to operate with spectrum management system 100 and with RPV systems as shown by DED DEV 114 associated with RPV SYS 4 .
- DED DEV 114 may be included in the base unit and/or in the drone in the form of a chip, for example, as an integrated circuit (IC), an ASIC (application-specific IC), a SOC (system-on-chip), among other types of chips, or may be an add-on system with communication capabilities.
- IC integrated circuit
- ASIC application-specific IC
- SOC system-on-chip
- RPV race which may involve several RPV systems, for example RPV SYS 1 -RPV SYS 4 , operating in the potentially interfering RF environment and/or with the event setup.
- the information may be stored in FAMA database (DB) 104 .
- FAMA DB 104 may store and organize the predefined information for processing by spectrum manager 102 to allocate the frequency or set of frequencies to each RPV system, and additionally or alternatively to allocate the power level limits.
- the predefined information may address data which may be relevant to the potentially interfering sources to enable spectrum manager 102 to allocate the frequencies and/or power level limits taking these potentially interfering sources into account.
- Operational radius the maximum radius of operation of all systems participating in an event relative to the location (a above);
- Time slot the period of time allocated to an event including information about event start time and finish time
- regulatory limitations the regulatory limitations applicable to the wireless systems to be operated during the event and may take into consideration the operation of the potentially interfering sources, among many other parameters associated with regulation compliance (e.g. restrict use of reserved channels and provide bandwidth limitations, location of existing radars and other RF transmission sources);
- Output power limitations the power limitations applicable to each RPV system, and may be prescribed by the regulatory limitations (d above) or to prevent interference between adjacent channels for geographically close systems;
- channels the channels which may be occupied or previously assigned (e.g. by regulatory limitations) to potentially interfering sources such as radars and other outside sources.
- None-player channels the channels which may be occupied by spectator wireless devices and by those of players and non-players in one or more neighboring events;
- Priority the prioritization rules which may be used to allow each RPV system to select between channels from the set of channels which it has been allocated by the spectrum manager.
- local manager 202 may send spectrum manager information regarding the instructions provided to the computing devices (i.e. updates the spectrum manager regarding the changes). Local manager 202 may redistribute the allocation of channels and/or power level limits provided by spectrum manager. In some embodiments, local manager 202 may transmit the channel monitoring information to spectrum manager 102 and the spectrum manager may perform the assessment and may provide the computing devices with the respective instructions, which may include reallocating the set of frequencies and/or power level limits allocated to each computing device. Alternatively, local manager 202 may send its assessment to spectrum manager 102 who responsively may send its instructions to the computing devices, including reallocating the set of frequencies and/or power level limits provided to each computing device if necessary.
- local manager 202 may assess the channel quality of the allocated channels for each RPV system and may transfer this information to spectrum manager 102 and/or to FAMA DB 104 for storage and processing.
- Local manager 202 may additionally assess channel interference from the possible interfering sources (e.g. radar 20 and interfering neighborhood devices 30 ) and may also transfer this information to spectrum manager 102 and/or to FAMA DB 104 for storage and processing. It may be appreciated that use of the monitoring and/or assessment information provided by local manager 202 prior to the start of an event may be particularly advantageous over the “off-line” mode of operation as the “off-line” mode requires predefining the data stored in FAMA DB 104 .
- the predefined data stored in FAMA DB 104 may not necessarily reflect actual channel conditions at the start of the event.
- a computing device may receive a single frequency assignment from spectrum manager 102 based on the predefined data input in FAMA DB 104 and may set up a wireless link for the RPV system over the assigned frequency.
- the RPV system remains on the same channel during the whole session.
- This mode may be similar to the “Off-line Mode”—Single Frequency Assignment” with the exception that the single frequency assignment and/or power level allocation from spectrum manager 102 is based on the data input in FAMA DB 104 based on channel quality/interference monitoring and assessment made prior to the start of an event by local manager 202 .
- FAMA DB 104 may check the game settings input by the organizer to evaluate if they correspond with the event settings associated with the game and to corroborate that there is no contradiction with other events which may occur at substantially the same time and/or be geographically proximal.
- an evaluation may be made to determine if the total number of available channels which may be allocated to the RPV systems simultaneously participating in the game exceeds the number of RPV systems.
- the evaluation may be made by spectrum manager 102 , by local manager 202 , or by FAMA DB 104 . If no, continue to 507 . If yes, continue to 508 .
- the organizer may be notified (on the computing device) that the game settings entered do not correspond with the predefined data in FAMA DB 104 associated with the particular game.
- the organizer may be notified that the number of available frequencies is limited to three per user and the organizer requests 5 frequencies.
- FAMA DB 104 may be updated with the game settings input by the organizer.
- the organizer may receive on the computing device an indication that input of the settings was successful.
- FIG. 6 is a flow chart of an exemplary method 600 of allocating frequencies to RPV systems prior to the start of an event associated with a RPV game (e.g. RPV racing) using the spectrum management system, according to an embodiment of the present invention.
- spectrum management system 100 and 200 For clarity purposes, reference is made to spectrum management system 100 and 200 .
- the exemplary method described may be implemented using more or less step, and/or a different sequence of steps, and that, although described with reference to setting up an event for a game, the method may be applied for setting up non-game related events which may include use of a spectrum management system. It may be further appreciated by the skilled person that the exemplary method may be equally apply to the “Off-line Modes” of operation and to the “On-the-fly Modes” of operation.
- a player may login into the spectrum management system through a computing device which may be LT 108 , MOB 110 , TAB 112 or DED DEV 114 .
- game settings which may include the location of the event and the time slot of the event may be input by the game player by means of the computing device.
- FAMA DB 104 may check the game settings input by the player to evaluate if they correspond with the event settings associated with the game. If no, continue to 607 . If yes, go to 608 .
- a check may be made if the spectrum management system includes one or more local managers 202 . If no, continue to 609 . If yes, go to 610 .
- local manager 202 in spectrum management system 200 may assess the channel quality of the available RPV system channels and possible channel interference from the potentially interfering sources prior to the start of the event.
- Embodiments of the present invention may include apparatus for performing the operations herein.
- This apparatus may be specially constructed for the desired purposes, or it may comprise a general-purpose computer selectively activated or reconfigured by a computer program stored in the computer.
- the resultant apparatus when instructed by software may turn the general purpose computer into inventive elements as discussed herein.
